SPECIFICATION forming part of Letters Patent No. 662,718, dated November27, 1900.

Application led August Z5, 1900.

T0 all whom it may concern:

Be itknown that I, OLIVER F. GOOD, a citizen of the UnitedStatesresidingat Dayton, in the county of Montgomery and State of Ohio,have invented certain new and useful Improvements in Explosive-Engines;and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to the letters of reference marked lthereon, which form a part oli' this specification.

This invention relates to new and useful improvements inexplosive-engines, and comprises a double-cylinder engine, the detailsof which will be hereinafter specified.

The object of the invention is to providea double-cylinder engine withas few valves as possible, thereby greatly simplifying the engine,making it less liable to be troubled with leakage, and providingaltogether a more efficient and reliable engine.

In a detail description of my invention reference is made to theaccompanying drawings, of which- Figure lis a side elevation of myimproved engine. Fig. 2 is a top plan view. Fig. Sis a horizontalsection through the cylinderhead, as shown in Fig. 4, the'section beingtaken on a line between the two leversL and L'. Fig. 4 is an elevationof the cylinderhead and valve-box. Fig. 5 is a section on the line az'of Fig. 4. Fig. 6 is a partial sectional elevation of the devices forregulating the admission of gas to the mixing-chamber. Fig. 7 is an endelevation of the gas-` valve box.

In a detail' description of my invention similar reference charactersindicate` corresponding parts.

A A. designate the cylinder head or heads, with integral valve-box O andinclosed by water-jackets A'.

B B designate two parallel power-cylinders communicating with thecompression-chambers in the head or heads, (see Fig. 3,) which chambersare divided by Walls B' B', which have a water-space B". The interiorspace within the valve-box O is separated into two chambers F and F',the former being the mixing-chamber and the latter being the ex- SemalNo. 27,965. (No model.)

haust-chamber, said chambers being common to both cylinders. Walls O'provide seats for checkvalves D and D', valve D being the inlet-valvecontrolling the admission of the eX- plosive mixture, which consists ofair and gas, from chamber F to the compressionchambers, and valve D'being an exhaustvalveA for both cylinders. The admission and exhausttake place through the inlet and eX- haust-port E.

R designates an escape-opening from the exhaust-chamber F'.

Gas is admitted to the mixing-chamber F through valve I-I, and air isadmitted. to said chamber F through an opening I, having a pipe or otherconnection. (Not shown.) Ohamber F supplies both cylinders throughvalves .I and J', which open into the compression-chambers in the heads.One of said valves is held open during one revolution of the crank andthe other is held open during the next revolution. These valves .I andJ' allow an expulsion of the burned gases on every alternate instroke ofthe pistons and admit fresh air and gas on every alternate outstroke.The said valves control the communication between the port Eand thecompression-chambers in the heads, port E being common to both valves,as shown. in Fig.

L and L', the former being fulcrumed at L" and lever L having itsfulcrum at L"". Lever L is connected to an eccentric or cam rod M'. Thelever L has a projection N, against which the lever L' makes contactwhen the throw of the eccentric is toward the crank. When theeccentric-rod M moves toward the crank-shaft, valve J' opens through themovement of lever L and valve .I opens when the lever L' is moved by theeccentric-rod M moving away from the crank-shaft. rPhe operation of thevalves is reversed on each. operation of thelevers-that is to say, onevalve opens while the other closes. The gas-valve H is operated by thelevers L and L' through tappets O and O', which are rigidly attached tosaid levers. These tappets or plates O and O' have their contact edgesprovided with grooves a, which engage with tappets or plates q and q',the latter plates being attached to a slide t, which moves on a guide orpost t', projected from a slide T. The slide T moves 3. These valves areoperated through levers IOO in a dovetail groove l) in the side of thevalvebox I-I ofthe gas-valve. The end of the slide T projects at rightangles in a position to engage the stem of said gas-valve H. Movement isimparted to the slide F through the levers L and L and the tappet-platesO and O. The said tappet-plates O and O engage with the projections orplates q and q upon each stroke of the eccentric toward and away fromthe crank, depending, of course, upon the positions of the plates qandq', which are controlled by a governor S. The said plates q and q aresubject to movement at right angles to the movements of the slide T, andmovement is imparted to them through the slide 't by a bell-crank, onearm c of which has a slot c', which receives a stud e on a side of theslide t, and the other arm e of said bell-crank is connected to thegovernor-rod d. The arms c and e are connected by a shai'tf. When thespeed of the engine reaches a certain point above the desired speed, theslide t will move to a position that shifts the tappet-plates q and q'out of a position to be engaged by the tappet-plates O and O', and nogas will be admitted through the valve I-I at that time. If the speed ofthe engine diminishes or the engine for any reason shouldstop, thegovernor will cause the slide 't to drop to a position lower than theplane of the tappets O and O', and thus the said plates Q and q' willnot be within reach of the tappets O and 0. It will be thus seen thatthere is no danger of the gas-valve remaining open when the engine stopsat any point of the stroke.

In an explosive-engine, thecombination with two power-cylinders, of a head having two separatecompression-chainbers, an integral valve-box on said head and occupyinga position midway of said head, a mixing-chamber, exhaust-chamber, and apassage E between said mixing-chamber and exhaustchamber, two valvescontrolling the communication between said mixing-chamber,exhaust-chamber, and passage, an inwardlyopening valve for eachcompression-chamber in the cylinder-head and controlling the admissionof explosive mixture from the passage E to said compression-chambers,and means for operating said valves.
